Treated very badly by very *********** staff

Trying to change wrong information (error on FNB side) for FNB In-Contact. been to the bank - no help. Spent about three hours on the phone yesterday, to no avail. Been cut off numerous times, phone were put down on me twice, some very helpful and friendly but *********** person put me through to discovery medical aid. Lodged a complaint yesterday that seems to have gone missing as well. They should just put a recorder there to record the complaint before discarding it - can save them lots of money.
